Answer 2

Calculation of the Cost of the Blouse and the Remaining Money

To calculate the cost of the blouse and the amount of money Nadya has left, we need to follow the given information step by step.

1. Nadya's father allocated 600 rubles for updating her wardrobe. 2. The dress costs 25% of the allocated amount. 3. The trousers cost 70% of the dress's cost. 4. The blouse costs 20% of the remaining amount after buying the dress and trousers.

Let's calculate the cost of the blouse and the remaining money for Nadya.

Step 1: Calculate the cost of the dress: - The dress costs 25% of the allocated amount. - 25% of 600 rubles = 0.25 * 600 = 150 rubles.

Step 2: Calculate the cost of the trousers: - The trousers cost 70% of the dress's cost. - 70% of 150 rubles = 0.7 * 150 = 105 rubles.

Step 3: Calculate the remaining amount after buying the dress and trousers: - The remaining amount is the allocated amount minus the cost of the dress and trousers. - Remaining amount = 600 rubles - (150 rubles + 105 rubles) = 345 rubles.

Step 4: Calculate the cost of the blouse: - The blouse costs 20% of the remaining amount. - 20% of 345 rubles = 0.2 * 345 = 69 rubles.

Therefore, the blouse costs 69 rubles.

Step 5: Calculate the amount of money Nadya has left: - The remaining money is the remaining amount after buying the dress and trousers minus the cost of the blouse. - Remaining money = 345 rubles - 69 rubles = 276 rubles.

Therefore, Nadya has 276 rubles left.
